Data recovered from a flight simulator seized from the home of the pilot of a missing Malaysian plane has been sent to international investigators for verification.

"As far as the simulator is concerned, we have forwarded the information to international parties to verify, and very shortly I believe the Inspector-General of Police will be able to give information of the current situation," Defence and Transport Minister Hishammuddin Hussein told reporters.

Captain Zaharie Ahmad Shah, 53, the pilot of the plane, came under after Prime Minister Najib Razak said the change in plane's direction was consistent with a "deliberate action" by someone on board. Investigators raided Zaharie's house and seized the simulator from his house.

They then dismantled and reassembled it to analyse its data.
